Fault Region Extraction of Electrical Equipment in Infrared Image by Using an Extended Mean Shift Method
摘要
Abstract
In infrared images, fault regions in electrical equipment often appear at high brilliance. However, some existing methods to extract the region may be influenced by characteristics of infrared imaging, such as low contrast and boundary blur, thus obtaining a larger region than the real fault region. We propose an extended mean shift algorithm by introducing the weight factor associated with the neighboring pixels. To simultaneously improve the efficiency of the clustering method, the original mean shift clustering method to iterate in the image is abandoned. The threshold segmentation mechanism from top to down is merged in the mean shift algorithm. The speed of the clustering pixels is increased, and the fault region is extracted effectively. Experimental results show that the region extraction performance of our method is better than some existing methods and the traditional mean shift clustering method.关键词
